IPC: B29D30/08
Filed: 1946-08-26
Abstract: 616,081. Pneumatic tyres. WITT, E. W. Aug. 26, 1946, No. 25511. Convention date, Aug. 24, 1945. [Class 144 (i)] In a machine of the kind described in Specification 566,341, for making tyre casings by winding strip cord material about a rotary drum, means are provided whereby the axis of rotation of the strip-feeding device passes through the geometrical centre of the drum irrespective of the relative obliquity of the two axes. To this end, means are provided for effecting lateral adjustment of the strip-feed axis to compensate for altered inclination of the drum-axis. Means are also provided for varying the relative speeds of rotation of the strip-feed and drum. As shown, the building- drum 13 is mounted on the lower end of a shaft 12 the upper end of which is fitted with a worm-wheel 25 meshing with a worm 26 on a driven shaft 20. The latter is mounted between arms 22 which are vertically-adjustable in a supporting-bracket 8 to vary the inclination of the shaft 12. The tyre-material (in strip form) is fed from a reel 37 on a bracket 35 carried by a vertical shaft 27 which is horizontally-adjustable to ensure its vertical alignment with the centre C of the drum. The strip is led from the reel 37 over guide-rolls 39, 40, the latter being vertically-adjustable for horizontal alignment with the drum-centre. The strip-tension is controlled by means of a spring-loaded brake. The shaft 27 is driven from the main shaft 51 through a worm-gear 34; and, the shaft 12 by chain-and-sprocket gears 60-64 and worm 25. To vary the relative speeds of the rotating drum and the orbital rotation of the reel 37, an idler changespeed gear 57 is fitted in the transmission to the shaft 12.

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1934-09-07
Abstract: 440,507. Cigarette making machines. WIX, A., 338, Goswell Road, London, MAY, R. F., 9, Manor Road, Potters Bar, Middlesex, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earls Court, London. Sept. 7, 1934, No. 25802. Addition to 424,492. [Class 130] The parent Specification relates to a machine for making cigarettes provided with filter tips in which lengths of tobacco cut from a continuous rod are moved out of alignment therewith and associated with filter tips and carried, in parallel bores in an intermittently rotatable carrier, axially into engagement with means for applying a continuous paper strip to produce a continuous cigarette rod. According to the present invention, comb-like elements engage the tobacco at a number of points and avoid axial compression thereof during its movement into and /or its ejection from the bores in the carrier. The tobacco after being compressed by rollers 6, 6a is fed into one of a series of bores 1a in a sleeve 1 which is rotatably mounted in a casing 2. To avoid axial compression, a comb 7a, which extends into the sleeve 1a enters a slot 1b in the bore to engage the tobacco and move forwardly with it. The comb 7a is carried by a slide 7b which is reciprocated on a pivoted lever 8 and is moved into and out of engagement with the tobacco on orbital paths by a cam 8a. A knife 9 severs the tobacco in the bore which is supplied with a filter tip 10 by a plunger 11a. The bores 1a have a slightly larger diameter than the finished cigarettes and are tapered outwardly and preferably accommodate double length tobacco portions and filter tips. The associated tobacco portions and filter tips are ejected on to the paper strip 13 by comb-like elements 14a on a chain 14 which engage the tobacco through the slots 1b. The chain 14 is carried by sprockets 14b mounted on an oscillatable frame 15 which is raised and lowered by a cam 15a. In modified forms, the filter tips are inserted into the bores before the tobacco, or are supplied behind the lengths of tobacco. The Provisional Specification refers to Specifications 311,827, [Class 130], 427,125, and 432,482.

Title: Improvements in or relating to electric meter constructions
IPC: G01R11/60
Filed: 1938-09-03
Abstract: 518,786. Supply meters. BRITISH SANGAMO CO., Ltd., (Sangamo Electric Co.). Sept. 3, 1938, No. 25828. [Class 37] A maximum demand meter in which the maximum indicator is advanced by the driven element of a clutch which is periodically disengaged and returned to zero position has the driving and driven clutch elements mounted in proper relationship upon a stationary arbor fixed to the frame. A worm 2 on the meter shaft 1 drives a worm-wheel 3 on a shaft 4 having worms 7, 8 cut on it. The worm 7 drives the usual counting train, while the worm 8 drives the maximum demand mechanism through gearing 9, 11, 12. The pinion 12 is a part of a friction driving clutch, its face normally contacting with a face of a member 15, Fig. 3, against which it is held by a spring 28. This clutch is opened and closed by a lever 36 operated by the timing mechanism. The member 15 has formed on it a pinion 33, to which is secured a disc 34. This drives a disc 47 through pins 35, 50, 48 and one or more loose discs 49 so that one or more revolutions of the driven disc 47 may be effected while permitting the driving disc 34 to be returned to its initial position without affecting the position of the driven disc 47, which is left at its position of greatest displacement. A loose gear-wheel 44 is driven from the disc 47 through a spring washer 45 and drives registering pointers 23, 24, 25 for the maximum demand through gearing 51, 54, 57, 58, 60. A ratchet-wheel 53 prevents reverse rotation. The members 12, 15, 49, 47, 44 are mounted on sleeves 85, 43 which rotate on fixed arbors 29, 30 from which they can be removed by longitudinal movement. The upper end of the arbor 29 rests in the lower end of the arbor 30. The driving disc 34 is returned to its initial position when the clutch 12, 15 is opened at the end of each time interval by means of a sector 37 meshing with the pinion 33 and operated by a weight or spring. At the end of a monthly period the driven disc 47 is reset to zero by means of a lever 68, Fig. 7, mounted on a shaft 69 to which is also fastened a sector 70 engaging a. pinion 46 fixed to the disc 47. The position of the lever 68 indicates the maximum demand during the monthly period and may be extended to form a pointer moving over an arcuate scale. Resetting is effected by turning back a lever 68 to a stop 71, corresponding to the zero position of the disc 47. The pointers 23, 24, 25 are held stationary during this operation by the ratchet 55, relative movement between the disc 47 and gear-wheel 44 being permitted by the slipping of the spring washer 45. During the following monthly period the pointers 23, 24, 25 are advanced to show the maximum demand added to the previous maximum demand. In a modification the pointers 23, 24, 25 are held stationary by a ratchet during the recording period and are advanced by the amount of the maximum demand during that period by the resetting means. Specification 475,512 is referred to.

Filed: 1967-06-06
Abstract: 1,194,023. Cathode-ray tubes. R.C.A. CORPORATION. 6 June, 1967 [15 June, 1966], No. 26138/67. Heading H1D. In the direct photographic process for fabricating the mosaic phosphor screen of a shadow mask cathode-ray tube, wherein light is projected from a point source through the apertures of the shadow mask to expose discrete areas of a photosensitive layer applied to the screen support, misregister of the discrete areas with the impingement spots on the screen of the electron beam is reduced below a chosen value by measuring the three-dimensional misregister at each of a plurality of points distributed over the surface of the screen of an operating tube, and employing these measurements to determine, for the surface of an optically refracting member introduced between the point source and the layer, the slopes, at each point corresponding to the said plurality of points, which are required to ensure the desired degree of correction of the misregister. The surface of the refracting member is determined by a least squares fitting of a bivariant polynomial to the calculated slopes; details of the calculation are given. The computed surface is machined in stainless steel by a numerical control milling machine, whereafter a flat glass plate may be placed on the mould and heated to cause it to sag into the mould, whereby the upper surface of the glass acquires the contour of the mould surface, and the lower surface may be ground off flat. The refractory member, of which a separate one is produced for each phosphor dot colour, may alternatively be of a plastics material. The measurements of misregister may be made in a tube already partially corrected by prior art methods.

Filed: 1919-10-25
Abstract: 157,570. Russell & Co., Ltd., J., and Mercer, G. H. Oct. 25. 1919. Drawing; dies.-In an apparatus for drawing wholly or partly tapered skelps or tubes for forming poles for telegraph, telephone, tramway, lighting, power-transmission, and other purposes, a tapered or partly tapered strip is drawn through a pair of movable dies in the form of sectors each involving two radial edges and a forming- surface less than a complete circle. In the form shown, the first portion of the grooves in the dies 4 is of uniform cross-section and the second portion of gradually decreasing crosssection to produce a tube partly cylindrical and partly conical. The grooves may be semicircular, pear-shaped, &c. The dies 4 are carried by sectors 2 to which are connected toothed sectors 10 engaging worms 11 on a shaft 12 which is provided with a series of pulleys 13 of different sizes, on any one of which is coiled a chain 14 connected to the carriage 7 of the draw-bench so as to produce the desired taper. The chain 14 is initially slack so that the first portion of the tube may be cylindrical. The sectors may be restored to their initial position after drawing by a handle 15 assisted by balance weights on cords 17. The plane of the axis of the tapered portion of the grooves may be inclined upwardly or downwardly to the plane of the axis of the cylindrical portion so as to produce a blank having a slight space to provide for butt welding. The sectors may be connected to the carriage by two pairs of chains, one pair extending from the carriage over separate pulleys, to each of which is connected a second pulley carrying a chain connected to one of the sectors and extending beyond the same and carrying weights. In another form the sectors may be linked to a split nut traversed by a screw operated independently of the carriage by variablespeed gear. The sectors are restored by balance weights when the nut is released.

A pipette comprising a barrel 19 in which a piston 24 is reciprocated by a plunger 44 through indexing member 37 having means such that the length of the intake stroke is shorter than the length of the dispensing stroke. The indexing member has six equally spaced radial teeth 39, as shown in Fig. 10, and six circumferentially spaced axially extending slots 41, and 42 (of two lengths). The rear face of piston member 24 has radial teeth 35 and are on more axially extending slots 32 in permanent engagement with inwardly projecting keys 33. On the first forward stroke push button 47 is depressed engaging the surface 69 of indexing member 37 with the slope 61 of tooth 35 causing the indexing member 37 to rotate to bring key 33 into alignment with short keyway 41 so that the stroke of the piston is limited by engagement of the key 33 with the shoulder 43. On releasing push button 47 the spring 56 pushes piston member 24 back up the barrel for the intake stroke causing the key 33 to disengage from slot 41 and causing counter clockwise rotation of indexing member 37 due to interaction of surfaces 61 and 66 this brings the key 33 adjacent to slot 42 in a similar position to that shown in Fig. 10. The button 47 is then fully depressed, and, in a similar fashion to the first forward stroke, the key 33 is slid into keyway 42 causing a longer stroke to dispense all of the liquid in reservoir 59.

Title: Therapeutic cyanophenoxazine derivatives
IPC: C07D265/38
Filed: 1960-07-28
Abstract: The invention comprises compounds of the general formula <FORM:0897158/IV (b)/1> and their acid addition salts wherein A is a C2-4 alkylene chain separating the nitrogen atom and the residue Z to which it is attached by at least 2 carbon atoms and Z is di-loweralkylamino, N-pyrrolidinyl, N-piperidyl, C-(N-lower alkyl)-piperidyl, N-piperazinyl, N1-lower alkyl-N-piperazinyl, N1-formyl-N-piperazinyl, N1-carbethoxy-N - piperazinyl, N1 - hydroxyalkylene - N - piperazinyl, N1 - acetoxyalkylene - N - piperazinyl, N1 - carbamoyloxyalkylene - N - piperazinyl, N-dialkylcarbamoyloxyalkylene - N - piperazinyl, N1 - hydroxyethoxyalkylene - N - piperazinyl or N1 - hydroxyethoxyethoxyalkylene - N - piperazinyl.  (The term "lower" indicates 1-4 carbon atom is the groups so described and the term "alkylene" unless otherwise indicated contains 2-5 carbon atoms.) The compounds of the invention are prepared by alkylating a phenoxazine of the formula <FORM:0897158/IV (b)/2> with a reactive aminoalkyl ester in an inert aromatic solvent. The cyano-10-(piperazinylalkyl)phenoxazines are advantageously prepared by alkylating the cyanophenoxazine intermediate with a haloalkylpiperazine having the free N-hydrogen of the piperazinyl moiety replaced by an easily removed substituent, for example, a benzyl, carbobenzoxy, carbethoxy, or formyl group, and removing the protecting group.  The resulting cyano-10-(piperazinylalkyl)phenoxazine is then further alkylated to form the N-substitutep piperazinyl compounds of the invention and compounds containing a terminal group capable of undergoing further reaction, e.g. N-hydroxyalkyl may be further acylated. Cyanophenoxazine is prepared by condensing a 2-halophenol with a chloronitrobenzonitrile to form 21-halophenoxy-nitrobenzonitrile which is reduced to 21-halophenoxy - aminobenzonitrile, formylated to give formamido-21-halophenoxybenzonitrile and finally cyclized, with hydrolysis of the N-formylcyanophenoxazine if this is formed. Specification 897,157 is referred to.

Abstract: 264,595. Hesketh, B. Oct. 21, 1925. Condensers have moving blades 1, Fig. 1, of uniform cross-section at any radius, the depth of which cross-section increases at a uniform rate from a minimum at a radius displaced 160 degrees or thereabouts therefrom. The fixed blades 2, Fig. 3, are formed similarly so that, when fully interleaved, the dielectric space is about zero, and the condenser follows a square law. One section of the blades need not vary uniformly to give a square law, but other laws may be followed by suitably varying the section and/or the shape of the blades. In making up, the moving blades are first threaded and clamped on the spinder 3 and, if desired, clamped to one another, and the fixed blades are wedged into place and screwed by rods 8 and end plates 10. When heat methods, for example welding, are used, the heat is localized, or by forming the rods 8 tubular and passing cooling water through them.
